Everything you need
Open Source & Purposefully Built
Carefully assembled set of features delivered to you as an Open Source tool to help you build better products, without locking you into any enterprise contract.
- Feature flags
- Classic feature toggles with on/off variations for enabling/disabling certain features.
- Experimentation
- Go beyond just boolean flags with multivariates enabling experimentation and A/B testing.
- Segmentation
- Target your audience with fine-grained conditions to control who sees what.
- Gradual rollouts
- Avoid big bang releases and roll out your features gradually to your users.
- Conditional variables
- Don't just store plain variable values, but also make them dynamic based on conditions for your runtime configuration needs.
- Consistent bucketing
- Makes sure the same user always sees the same variation across all devices and applications.
- Multiple environments
- No need to stop at just production and staging. Create as many environments as you need, or none at all.
- Tagging
- Tag your features accordingly so you only load the ones you need and nothing more, to keep your applications free of bloat.
- Force bucketing
- Allow your testers to force enable/disable certain features for themselves to gain higher confidence.
- Tracking
- SDKs support hooks for tracking how your experiments perform by integrating with your favourite analytics service.
- Testing
- Test your feature flags declaratively against multiple SDKs before deploying anything to gain maximum confidence.
- Universal SDKs
- Use JavaScript SDK in both Node.js and the browser, along with additional SDKs for cross-platform integration.
Manage with Git
Streamlined workflow for teams
Three simple steps to visualize the workflow:
Send Pull Requests
Your team sends Pull Requests to your Featurevisor project repository updating attributes, segments, and/or features.
Learn more
Build and upload to CDN
Upon merging your Pull Request, trigger your CI/CD pipeline to build the datafiles and upload them to your CDN.

Fetch and consume with SDKs
Fetch the datafiles from your applications and evaluate features using the provided Featurevisor SDKs.

Use cases that fit your needs
From basic feature flags to advanced experimentation, Featurevisor has you covered with several organizational and operational problems that are very common in the industry.
Progressive delivery
Roll out features gradually to a subset of users for more control and confidence — no more big bang releases.
Testing in production
Test features in your real production environment before exposing them to users — no more guessing based on staging.
Remote configuration
Change application behaviour in real time using variables — without redeploying a single line of code.
A/B testing & experiments
Run multivariate tests with weighted variations to validate hypotheses and make data-driven product decisions.
Trunk-based development
Ship to trunk continuously with flags hiding incomplete work — fewer merge conflicts, faster development cycles.
Feature ownership
Assign flags to teams so they can ship independently — with clear accountability and zero coordination overhead.
